The thermal melanin hypothesis posits that ectothermic individuals of larger size or from
colder environments exhibit darker cuticles due to melanin's efficacy in absorbing solar …

To improve thermoregulation in colder environments, insects are expected to darken their
cuticles with melanin via the phenoloxidase cascade, a phenomenon predicted by the …

Two of the most well-supported patterns to have emerged over the past two decades of
research in evolutionary biology are the occurrence of divergent natural selection acting on …

Reproductive barriers reduce gene flow between populations and maintain species
identities. A diversity of barriers exist, acting before, during and after mating. To understand …

In the Allonemobius socius complex of crickets, reproductive isolation is primarily
accomplished via postmating prezygotic barriers. We tested seven protein-coding genes …

Global climate change is expected to impact biological populations through a variety of
mechanisms including increases in the length of their growing season. Climate models are …

Speciation is the biological process of one species splitting into two or more new species,
and is the driving force of biodiversity on Earth. When such new species are formed, there …
